1) Only buy albums which were released in the last thirty days.
2) Only support bands which are less than five years old.
3) Avoid buying critically acclaimed albums.
4) Do not approach the counter with a band's shirt; you are the reason said band sold out.
5) Do not talk music with the clerks.
6) Do not let any sound escape from your person; they have already heard it done right.
Note: If these tips fail, simply ask the cashier if they have found another job.
